The nature and ndniiiitup es oi the inveutii'in will more tu l i' unneair ti-om the hillowiiu); more detaicl dez-ici'i ition.

in my prior application, serial No. 536% 6-"?? l have illustrated and described a, multiple unit tank cur in which he cradles :ire lougg 'itudinelly arranged. and the drums 0r tanks trmsversely itl'l'll'lf etl, so that the drums o1 tanks are )1'8V61]t(l from rolling motion longitiulinzilly ot the 'm' by the cradles. In the improvement of the present invention the car construction is such as to provide transversely arranged cradles for holding the drums or tanks longitudinally on the car, so that they are prevented from rolling motion laterally by the cradles; and clamping means is provided for securing the drums on the cradles, so that they cannot be raised therefrom and so that they cannot move longitudinally of the car until the clamping means is released.

The tanks used in the new car construction may be of about one-ton capacity and of generally cylindrical shape and provided with suitable valves, safety devices, etc. They may have an over-all length of about eighty inches, or somewhat less than the width of an ordinary railroad car.

For transporting liquefied gases, such as liquid chlorine, the safety devices should be of such a character as to permit release of the gases in case of fire or undue heating, before the pressure due to the heat becomes excessive. The safety devices may be in the form of fusible plugs which will melt at a relatively low temperature, for example, around 150 F. In case of injury or overheating of one of the tanks or drums, its contents will be released in a gradual and progressive manner, while the other tanks may retain their contents without injury.

The car construction is equally adapted for the transportation of full containers (filled with the liquefied gas) and empty containers, so that the car can be shipped with a load of full containers and returned with a load of empty containers, without delay other than that occasioned by the unloading and loading of the car. The car is, moreover, so constructed as to permit ready loading and unloading, while it is, nevertheless, designed and constructed to provide, as a part of the car structure, supporting and bracing means as well as cradles for holding the tanks with their axes horizontal and longitudinal of the car. In connection with each cradle and tank, means is provided for detachably securing the tank to the cradle so that the tank will be securely held in place, but that it may, nevertheless, be unfastened and removed when desired, and a new tank either empty or filled, inserted to take its place.

In constructing the car, the cradles and supporting means therefor are carried directly by the car frame so that the provision of the usual platform of a freight car is made unnecessary. However, the arrangement of a series of tanks longitudinally of the car presents an impediment to the easy and safe passage of the brakeman along the car, especially when the car is in rapid motion. In order to overcome this difiiculty, the car is provided with special passageways along the sides of the car, and also at the ends, so that the brakenian may easily and safely pass along the sides of the car from one car to another without danger, even during rapid travel of the ear in transit. The car construction as a whole, accordingly, enables a series of tanks of large capacity to be safely transported and held in place, but detached and removed and replaced when desired, while also enabling the brakeman to travel along the car, on gangways at the sides of the car, with the construction and arrangement of the car as a whole nicely balanced and with a load distributed in a substantially uniform manner transversely of the car.

The accompanying drawings illustrate the preferred construction of the multi tank car of the invention, the construction being shown in a somewhat conventional and diagrammatic manner, but it is intended and will be understood that the invention is illustrated by and not limited to the specific construction so illustrated and described;

In the embodiment of the invention shown in Figures 1 to 9, the frame or body of the car is made up of a central sill 1, constructed as a box girder, and a plurality of cross girders 2 supported by the central sill. Near the ends of the car other girders 3 of stronger construction than the girders 2 are provided. and trucks indicated at 4 are pivoted to the car at the girders 3. At the ends of the sill, girders 5 are arranged, and the girders 5 are connected to the girders 3 by longitudinal plates 6 and braces 7 as shown. Thus there is provided a stronger construction at the ends of the car than intermediate the ends, and this construction provides a suit able frame work for supporting and holding the car as a whole upon the trucks.

As shown more particularly in Figu e 4t, the girders 52 are of lighter construction. at their outer ends, and at the said outer ends they support a runway El, and a hand rail 9 at the outer side of the runway. lLlach girder 22 carries a series of blocks 10 and 11, the blocks 10 having their upper corners concave, While the blocks 11 have their upper inner corners concave. Each pair of hloclzs i0 and 11 forms between them seat "for engagement by a container 153, and the blocks 10 torn: between them a third seat for engagement by another container. Thus there is provided. on each girder 2 three seats, capable of holding; three containers, and the girders 2 are so spaced that each pair Will support three containers, the girders being; spaced. in such manner that the seats or cradles -termed by the blocks 10 and ii will be near the ends of the containers. it guard plate 18 is arranged at the inner side of each runuuty 8, and the said ,gguaii'd plates rest against the outer faces of the adjacent blocks 11.

In Figures 1 to 5, inclusive, the said means in the term oi rods 141:, which are pivoted. to the girders as indicated at 1!, a rod being arranged at each end oi? each container, th .t is, at each end oi? each cradle. it hook 1G is arranged to more on each rod, each hook l'iaving a bearing sleeve eitigagring the rod, and the hooks are designed to engage the chimes of the containers, as shown more particularly in Figure 5. Each ol. the hoolrs l6 rotatahly connected to a nut li threaded on the rod, and. it will be evident that by turning the nut the heel: may be moved longitudh nally of the rod, to engage or diser i .ne the hook With. the chim Each rod has a head 18 tor preventing entire disengagement ot the nut and hook.

Referring to Figure El, it Will be seen that the ends of each row oi? containers are flush, that is, in the same plane, and that each row ot containers is spaced apart from adjacent rows far enough to provide a passage be t een adjacent rows, so that the hr: liceinan, for instance, can pass the entire length oi? the or at either side, or may pass transi'mr-elv ot the car between any two adjacent so s of containers, and so that ready access may he had to the clamping nieai s between the containers. Hand rails 19 are arranged at the ends oi. the ear, the hand rails extending transversely from near one hand rail 9 to near the other, but being); spaced apart from said hand rails tar enough to provide a passageway.

ll ith the arrangement or the containers on the car in tl manner illustrated and de scrihed, the car when loaded is evenly balanced and the individual drums or containcrs are securely held in place agrz'iinst accidental u'ioveinei'it. The sidewise niovenient of the co miners is prevented by the transverse cradles and by the clamping means which clamp the containers on the cradles. The hmgitudinal movement of the containers on the car is prevent d by the I'llCl-lfil'ldl e renicnt oi} the son ners with the c 'adle. and by the clamping means. llhc. containers are thus ahle to withstand. the abrupt stops and starts of the car during": shitting]; or in i ansit.

the

pro d co l liti lit) The car is well adapted for loading and unloading since by releasing the respective clamping devices the full or empty drums can be lifted oil the cradles and other drums substituted and secured in place. A minimum of time is accordingly lost when the car reaches its destination, either in loading or unloading it, or in both unloading or loading it. The drums can be readily removed, for example, by means of an overhead crane, 311C. carried to their places of storage or of use. The car can thus be readily loaded and at its destination unloaded,

reloaded and again started in transit. It enables a relatively large number of tanks to be readily transported and safely secured in place against accidental movement during transportation.

The present invention, accordingly, presents advi'intages similar to those of an ordinary tank car, having a single tank, while it avoids the objections and disadvantages of such a. tank car, and, in addition, has added advantages in enabling liquefied gases to be safely transported in relatively large units and with the containers at all times accessible for ready inspection and testing. This inspection and testing is of particular importance where the gases transported are corrosive in character.

The multiple unit tank car of the present invention is also adapted for the transportation of noncorrosive products, such as casing-head gasoline, where it is imported to prevent escape of highly volatile dis solved gases, and where the containers are required to withstand the pressure which such gases may exert.

In the embodiment of the invention shown in Figure 12, the car indicated at 30 has a runway indicated at 31, arranged between the longitudinally extending tanks 32. lVith the tanks arranged in sets of three, the runway would have two tanks on one side and. one on the other, and in order that the load may be properly balanced, it is preferable that the runways be in sections, a section for each set of tanks, and that the sections of the sets be staggered. If the tanks are arranged in sets of four, the runways would have two tanks on each sid and would be continuous.

While I have illustrated and described the preferred. embodiments of the invention, I do not limit myself thereto, inasmuch as variations and modifications may be made therein without departing from the spirit and scope of the invention as set forth in the accompanying claims.
